Plant-Based Seafood and Animal Welfare Implications

Plant-based and fermentation-derived seafood alternatives are growing rapidly, offering significant potential welfare benefits by replacing products from wild capture fisheries and intensive aquaculture.

Key Facts

Global fish consumption exceeds 180 million tonnes annually, involving billions of individual animals
Plant-based seafood products including fish fillets, tuna alternatives, and shrimp analogues are now available from multiple producers globally
Whole-cut fish alternatives made from konjac, seaweed, and plant proteins are advancing towards restaurant and retail scale
Fermentation-derived seafood flavours can recreate the sensory profile of fish without requiring marine animal ingredients
The environmental footprint of plant-based seafood is generally substantially lower than wild-capture or farmed equivalents
Consumer acceptance of plant-based seafood has been growing as product quality improves
Cultivated seafood from cell cultures of fish, shrimp, and shellfish is in development and may be commercially available within years

Welfare Considerations

Plant-based seafood represents a welfare opportunity at enormous scale. Wild-caught fish experience fear, pain, and suffocation during harvest; farmed fish suffer from crowding, sea lice, and handling stress. Replacing even a fraction of this consumption with welfare-neutral plant-based alternatives eliminates suffering across billions of individuals annually. The welfare case for plant-based seafood is among the strongest of any food transition, given the scale of harm in conventional seafood production and the relative maturity of alternative products in some categories. Supporting the category through consumer purchases and retailer engagement accelerates cost reduction and quality improvement that makes broader adoption more feasible.

What You Can Do
